Which of the following is usually the weakest intermolecular interaction in small molecules?
A) Covalent bonding
B) Dipole-dipole interactions
C) London dispersion forces
D) Hydrogen bonding

Question

Quizplus · Accepted Answer

London dispersion forces are usually the weakest intermolecular interactions in small molecules. This is because they arise from temporary fluctuations in electron density, whereas dipole-dipole interactions and hydrogen bonding involve permanent dipoles or polar bonds, respectively. Covalent bonding is not an intermolecular interaction, but rather an intramolecular interaction within a molecule.
